Starting Resistors

Wärtsilä JOVYATLAS has over 30 years of experience in the production of starting resistors. Starting resistors are deployed to start large asynchronous machines with slip ring rotors. At first, the starting resistor in the rotor circuit is completely switched on and then switched off again in stages, until the full motor power is available. The starting resistor limits the starting current of the motor, thus increasing its momentum. The resistor and the grading of the stages determine the starting performance of the drive system. Starting resistors supplied by Wärtsilä JOVYATLAS are predominantly constructed of stainless steel grids and built into a zinc-coated steel panel enclosure. We will be most obliged to cater to your specific requirements.
